ANTI SACCHAROMYCES CEREVISIAE IGG ANTIBODIES

The anti-Saccharomyces cerevisiae antibody (ASCA) IgG test detects IgG antibodies against Saccharomyces cerevisiae. Similar to the ASCA IgA test, this test is used as a marker for Crohn’s disease. Elevated levels of ASCA IgG antibodies suggest an immune response to the yeast, supporting the diagnosis of Crohn’s disease. This test is particularly useful in conjunction with the ASCA IgA test to differentiate Crohn’s disease from other inflammatory bowel diseases, such as ulcerative colitis. It provides valuable information for diagnosing Crohn’s disease, guiding treatment, and monitoring disease progression.
